[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0018] like Figures 1 to 7 As shown, this embodiment provides a device including an intermediate body 1, with a flip-top connector 2 at the upper and lower ends of one side of the intermediate body 1 that flips and folds along the intermediate body 1. The intermediate body 1 includes a central block 101 and two mounting seats 102. A pair of vertically arranged and parallel drive shafts 103 are installed between the central block 101 and each of the mounting seats 102. A positioning block 201 is fixed on the flip-cover connector 2, and the positioning block 201 has a through hole for the drive shafts 103 to pass through. A gear synchronization mechanism 3 is installed between the two mounting seats 102 to drive the two flip-cover connectors 2 to move in opposite directions. Two flip frames 4 are installed between the two mounting seats 102, and the flip frames 4 are connected to the flip-cover connectors 2 via an elastic buffer mechanism 5. In this utility model, the flip-cover connectors 2 move synchronously through the gear synchronization mechanism 3, and the two flip frames 4 installed on the two mounting seats 102 are connected via the elastic buffer mechanism 5. The flip frames 4 are fixed to the outer shell. In this way, during the manual folding and unfolding of the outer shell, the elastic buffer mechanism 5 will buffer the movement, and then drive the flip-cover connectors 2 to move, thereby driving the two flip-cover connectors 2 to unfold through the synchronous transmission mechanism, thus realizing the unfolding of the display screen.

[0019] Each of the flipping frames 4 has a connecting part 401 on both sides that connects to the mounting base 102. The mounting base 102 has a positioning rotating column 402, and the connecting part 401 has a shaft hole 403 for the positioning rotating column 402 to be inserted. The mounting base 102 has an arc-shaped groove 404 with the positioning rotating column 402 as the center. The connecting part 401 has a limiting column 405 that is inserted into the arc-shaped groove 404 and moves along the arc-shaped groove. This allows the flipping frame to rotate around the center of the positioning rotating column, and under the limiting action of the limiting column and the arc-shaped groove, the flipping frame flips.

[0020] The connecting part 401 is provided with a clearance groove 406 for avoiding the mounting base 102 when the flipping frame 4 rotates, which facilitates the flipping frame to flip.

[0021] The gear synchronization mechanism 3 includes a pair of parallel rotating shafts 301 with non-circular cross-sections disposed between the central block 101 and each of the mounting seats 102. The rotating shafts 301 are fitted with complete gears 302 located at both ends of the rotating shafts 301. The complete gears 302 on the two rotating shafts 301 mesh with each other. The positioning block 201 is provided with incomplete gears 306 that mesh with the complete gears 302. When one of the flip-cover connectors 2 is rotated and unfolded, the other flip-cover connector 2 will be driven to unfold through the meshing of the complete gears 302 and the incomplete gears, thereby facilitating the folding and unfolding of the display screen.

[0022] A retainer 304 is installed between the two rotating shafts 301. A clamping spring 305 is installed between the retainer 304 and the complete gear 302, which is sleeved on the rotating shaft 301 and clamps the complete gear 302. This has a counteracting positioning effect on the complete gear 302, so that the complete gears can be locked in place.

[0023] The elastic buffer mechanism 5 includes a retaining block 501 mounted on the flip frame 4, and the retaining block 501 is provided with an obliquely arranged sliding groove 502. The flip cover connector 2 is equipped with a horizontally arranged sliding rod 503 that passes through the sliding groove and slides along the sliding groove 502. The retaining block 501 is provided with an installation cavity 504, and an embedding block 506 is installed in the installation cavity 504. An abutting block 508 that abuts against the sliding rod 503 is installed in the embedding block 506 via a spring 507. When the flip frame flips, the abutting block abuts against the sliding rod 503 under the action of the spring 507. When the flip frame is manually unfolded, the sliding rod can move along the sliding groove and compress the spring. This can absorb the instantaneous impact force and avoid damage to the hinge mechanism. After the spring is compressed to a certain extent, the sliding rod no longer moves along the sliding groove. At this time, the flip frame drives the flip cover connector 2 to unfold.

[0024] The embedded block 506 is equipped with a limiting groove 509 that linearly limits the contact block 508, thus linearly limiting the embedded block 506. The front end of the embedded block 506 is provided with a ramp 510, which facilitates the sliding rod to slide along the ramp.

[0025] A cover plate 6 is installed between the mounting bases 102 to cover the gear synchronization mechanism 3, thus ensuring a good overall appearance.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
